Técnica de hipotermia profunda y paro circulatorio total para clipaje de aneurismas cerebrales gigantes A case report regarding the deep hypothermia and total circulatory arrest technique for clipping giant cerebral aneurysms

Deep hypothermia and total circulatory arrest technique for facilitating clipping complex posterior circulation cerebral aneurysms is not a new technique; however, this case report deals with the first case treated at the Hospital Santa Sofia in Manizales (Caldas) and in the Colombian coffee-growing area. Our team reports a 53-year-old female patient who underwent surgery to clip a giant basilar artery aneurysm; closed-chest extrathoracic cannulation for femorofemoral cardiopulmonary bypass was used, involving total circulatory arrest, deep hypothermia and heparin anticoagulation. Cardiac arrest lasted 15 minutes. The patient did not require conversion to sternotomy. Blood outflow via femoral vein was sufficient to maintain cardiopulmonary bypass and induce deep hypothermia (18°C, retention of spontaneous circulation, and propofol infusion (3–5 mg · kg−1 · h−1)
